10 Claims.- (Cl, 161-26) This invention has reference to the art ofduplicating instruments, and particularly relates to a perforating and staining needle or instrument capable of simultaneously penetrating and staining several layers of, material for duplicating purposes.

Among the objects of my invention may be noted the following: to provide a'needle or instrument so constructed as to enable it to penetrate a plurality of thicknesses of material, such as paper or fabric, and at the same time to stain the material surrounding the line of penetration; toprovide a device of the kind stated which can be used to duplicate patterns and correct mistakes and inaccuracies made while producing the same; to provide a perforating device with means enabling it to be power driven and with means enabling it to mark several layers of material in one or more colors; to provide a duplex perforating and staining implement which'can be motor-driven and the driving means can be caused to operate upon placing theinstrument in position for a functional purpose; to provide a perforating and staining implement capable of being driven by power, and the implement and its power means capable of being freely adjusted and manipulated relatively to the work, and the power means set in operation when the executive end of the implement is caused to engage the work and thrown out of operation when the implement is removed from the work; and to provide details of construction enabling the implement to operate and function as stated in the foregoing.

With the above objects in viewand others which will be detailed during the course of this description, my invention consists in the'parts, features, elements and combinations thereof hereinafter described and claimed.

In order that my invention may be readily understood, I have provided drawings wherein:

- Referring to the drawings and particularly to Figure .1, the numeral 1 indicates a guide wire tautly' strung in any convenient place ,andmanw men, A trolley 2 is guided on said wire, and pend: ant therefrom are flexible supporting wires alto which asuitable motor is secured. The motor is housed in a frame 4 having acylindrical hand hold 5, terminating inasupporting cover 6, op erating as a cap or shield for themain perforating device "land auxiliary'perforating device These devices; 7 and 8 are each composed of a sheath of tubular, drawn or stamped and soldered or brazed metal, uniform in diameter to near the lower end, which is formedtapering, as at 9. The

lower end of each sheath is truncated, an'dfthe said tubular, members each contain the exetutive elements thereon The main device, midway the Figures 1 to 4. Between its ends the lever 13 is provided with a curved portion 16 whichexs tends around the longitudinal center of the sheath, thus avoiding contact with the perforating and staining device. At the outer end or the curved portion 16 of the lever 13, a stiff wire or rod 17 is pivotally connected, said wire extend ing lengthwise of and within the sheath, through the cap 6, and the hand-hold 5, and outside the motor-casing 4, whereon it ,is pivotally lionnected to one end of a switch 18 pivoted to the casing 4, between two contacts 19 and 20" sagas to close the circuit and convey the currentgto eitherside or member of the, duplex implement. Normally, the lever 13 is depressed, as at, the lefthand side of Figures 1 and 4, so as to ope'n the switch 18, by means of a flexible spring 21 setcured to the bottom of the'sheath and resting upon the top oi lever 13 between the wire 1? and the guide 14. The lower end of thesheath is also provided with a pressure roller 22 journaled on a bracket 23 fixed to the sheath. The

roller parallels the guide so as to pressragainst the body of the pattern within its edge, asshown in Figures 1 to 3, thus giving the implement antifrictional contact while in operation and reliev ing the hand ofstram. I n

As shown in Figures 4 to 7, inclusive, a plurality of lugs-24are spaced equidistantly about the-interior of the sheath '7, the same being adapted tosupport coiled springs 25, the upper ends. or

direct the implement, as presently described,-see

dle from turning or twisting within the sheath 7 during the operation of the needle, and also hold the needle centrally within the sheath and so as to operate within the bend 16 of the presserfoot. The needle consists of the tubular shank 29 which is contained loosely within the sheath, there being ample space between the two to enable the wire 17 to pass between the walls thereof and outwardly into cap and hand-hold and into engagement with the switchlever 18. The outer end of'the needle shank is composed of a rounded solid portion 30, and the inner end of said shank is provided with a nipple 31 internally threaded to receive the externally threaded outer end of the needle-body and reservoir 82. The needle body is hollow throughout its length and is tapered, as shown in Figure 4, and the chamber thereof communicates through the narrow passage 33 with the chamber of the shank 29. The passage 33 is through the head of the nipple 31 and an elongated tubular teat 34, said teat being adapted to receive the lower end of the flexible tube 35 of the bag 36 adapted to contain the staining liquid. The outer end of the bag is provided with a short, flexible neck 37 which passes through a slot 38 in the shank of the needle and is threaded, as at 39, into the sheath and into a nut-like closure 40 for the said bag. The. nut 40 and a shoulder 41 on the neck 37 tightly clamp the bag in position within the needle shank 29 and hold it normally as shown in Figure 4. The executive end of the needle, as shown in Figure 4, is formed into a penetrating point 42 above which are placed circumferentially of the tubular portion a plurality of apertures 43 extended into shallow grooves 44. The apertures enable the liquid in the needle to seep from the chamber of the latter, and the grooves hold a minute portion of the liquid insuring proper staining of the material during the reciprocation of the needle. The head 30 of the sheath is engaged by an eccentric 45 adapted to operate upon the solid head 30 of the'shank 29, said eccentric being carried by the stud-shaft 46, which is adapted to slide in the open-end groove 47 at the upper end of the sheath. The shaft 46 also carries adjacent the eccentric, but spaced therefrom, a bevel pinion 48 which meshes with a bevel pinion'49 carried on the free end of the flexible driving shaft 50 extending from the motor, as shown in Figures 1 and 4.

As previously suggested, the duplex character of the implement is carried out by giving the portion 8 thereof all the structural and characteristic features of the portion 7; and the two portions -7 and 8 are held in proper and intimate relation by the elongated, angular tongue 51 carried by the sheath 8, and the correspondingly elongated grooved, angular member 52 carried by the sheath 7. The tongue 51, while fitting in the groove snugly, may readily be shifted therein so as to enable the sheath 8 to be normally held with its guide and roller out of contact with the work as shown in Figures 1 and 4. The bag, not shown, of the portion 8 of-the duplex instrument, is

7 adapted to carry a fluid of different color from say, the bag of the portion 7 may carry green ink or fluid, while the bag of the portion 8 may carry red ink or fluid. An open-end groove 47 is provided near the upper end of the sheath 8, and this groove is adapted to register with the groove 47 in the sheath 7 so that, when the sheath '8 is shifted outwardly in the cap 6 to functional position, the stud-shaft 46 and the driving mechani'sm carried thereby may be shifted from sheath 7 to sheath 8 so that the eccentric 45 may operate upon the solid head of the needle shank within the sheath 8. As shown in Figures 1, 4 and 5, each of the sheaths 7 and 8 is provided with a latch 53 held in either of two positions by thumb nut 54, the said latch being adapted to be shifted circularly into engagement with one headed end 55 of the stud-shaft 46 which carries the eccentric and bevel gear. The functional position of the latch is shown in Figure 5, while the inoperative position of the latch is shown in Figure 4. Thus, regardless of the portion of the duplex implement which is in operation, the needle actuating mechanism may be held properly in the groove 47 and 47 in position to accurately centrally engage the solid head of the needle shank.

From the foregoing description of the details of construction, the following mode of operation will be readily understood. Normally, the driving mechanism, including the eccentric 45, will be held in the slot 47 so that the eccentric can actuate the needle in the portion 7 of the implement, the portion 3 of the implement being elevated out of functional position as shown in Figures 1 and 4. Normally, the portion 7 of the implement will be utilized because it is necessary that the green ink, for example, shall be the main coloration of the duplicated patterns, the red ink of the portion 8 of the implement being intended to indicate corrections only, the portion 8 consequently being utilized only semi-occasionally when mistakes have been found and corrections are to be made. The implement, with the parts in the position of Figure 1, is held in the hand with the thumb seated in the grooved member 10, and the fingers extending around the two portions 7 and 8, as indicated at 11, the operator thus being able to hold the two portions 7 and 3 in proper operative relation at all times and steadily for manipulation as required. The trolley 2 is mounted on the guide-wire 1 and by gripping the hand- L hold 5 the entire implement can be shifted quickly and easily to approximately the position desired for beginning the work. The current wire or connection to the motor (not shown) will be extended in any direction desired to plug in for power. The patterns 15 being made of suitable material, and it being desired to produce therefrom an indefinite number of duplicates, as from the material piled as shown at 56, Figure 4, on the table or support 57, the implement is gripped as explained, and its executive end is lowered so that the guide 14, of portions 7, will engage the edge of the pattern 15 and the pressure roller 22 will engage the body of the pattern back of its guiding edge. Thus positioned, the needle of the implement will be enabled to penetrate the materials 56 below and beyond the edge of the pattern 15; and as the implement is pressed downwardly upon the pattern 15, the lever is caused to actuate the wire or rod 17 and thus shift ver- 1.

7 of the implement and as the needle is forced a downwardly will penetrate the various thicknesses of material 56, and the liquid in the needle will flow therefrom throughthe apertures 43 and into the grooves 44 and by capillary attraction will be retained by the materials and saturate the same a short distance surrounding the needle penetration. Ihis normal operation will continue until, for some reason, it is desired to utilize the portion 8 with the red ink or fluid, as when a mistake is discovered in the reproduction of the pattern 15, whereupon the operator will lift the implement from the work, thus enabling the spring 21 to depress the guide-lever i3 downwardly which will shift the switch 18 downwardly and break contact at 19. Now the latch 53 is released and turned downwardly out of the way so as to release the stud-shaft 46 carrying the cam 45. The portion or sheath 8 of the implement will now be depressed so that it may be slid downwardly on the sheath 7 so as to cause the slots 4'? and i7 to register. The stud-shaft 46 will now be shifted over from the slot 47 into the slot 4'1 of the sheath 8, whereupon the latch 53 of the latter will be turned upwardly into contact with the head 55 of the stud-shaft 46, thus holding the latter in the proper position for engagement with the head 30 of the needle shank 29. Then the portion 8 of the implement will be still further shifted relatively to the portion '7, so that the executive end of its needle and the guide and pressure roller may be caused to extend beyond the portion '7, and to engage the work as desired independently of the portion 7, the latter now being out of operative position.

Pressure, by the operator, upon the implement will cause the. guide and roller to engage the pattern-edge and surface, respectively, and as the guide-lever 13 rises, its connected switch-rod 17 will shift the switch 18 into engagement with contact 20, whereupon the motor will cause the cam 45 to actuate the needle of portion 8. This will continue untilit is desired to again use the instrument '7, whereupon the instrument 8 will be rendered inoperative, the cam 45 shifted over and fastcnedto instrument '7, whereupon the latter will be again ready for operation, all as will be readily understood from the foregoing description.
